Steam condenser with heat exchanger and a cooking oven with such steam condenser

A steam condenser for a cooking oven having a housing, having side walls and having at least partly open front side and back side to facilitate flow of cooling air through the steam condenser, and a heat exchanger located in said housing, which serves as a condenser, wherein the heat exchanger comprises a number of connected finned tubes through which water vapor with other gases from the cooking oven are guided, wherein the steam condenser comprises a condensate drainage system,

• the finned tubes are arranged between the side walls of the housing and in a descending manner, such that each tube has one end attached to the side wall of the housing higher than an other end, while also each two adjacent ends of adjacent tubes are located one higher than the other, wherein the adjacent ends of the adjacent finned tubes are connected by 180° connectors, such that the finned tubes are interconnected in a zigzag manner, wherein the highest or the lowest of the finned tubes is further connected to a final descending tube which is provided with orifices in an upper part and located on the side of the final descending tube that is facing away from the flow of the cooling air.
